Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Combination Figure 1 Shown:

[0016] A high-efficiency purifier for precision liquid circulation includes a waste tank 1, an inlet tank 11 on one side of the waste tank 1, a funnel-shaped filter screen 12 inside the inlet tank 11, an outlet tank 13 on the other side of the waste tank 1, two microporous membranes 14 between the inlet tank 11 and the outlet tank 13, an evaporator 2 connected to the outlet tank 13 by a pipe, a reverse osmosis membrane tube 21 inside the evaporator 2, the reverse osmosis membrane tube 21 being a serpentine pipe, the inlet of the serpentine pipe being connected to the outlet tank 13 by a pipe, the pipe being equipped with a motor and valves for drawing the circulating waste liquid into the reverse osmosis membrane tube 21 to purify the liquid.

[0017] Evaporator 2 is connected to the top of condenser 3 via a pipe. An exhaust pipe is located above condenser 3 and connected to activated carbon adsorption box 8 for adsorbing and treating the discharged impurity gases. Waste liquid tank 6 is located at the bottom of evaporator 2 and is connected to the outlet of reverse osmosis membrane tube 21 via a pipe for holding impurity waste liquid.

[0018] The condenser 3 is connected to the top of the multilayer membrane separator 4 via a pipe. Inside the multilayer membrane separator 4, from top to bottom, are arranged a microfiltration membrane layer 41, an ultrafiltration membrane layer 42, and a nanofiltration membrane layer 43. Each of these layers consists of three identical membranes forming a multilayer membrane, with the filtration diameter gradually decreasing, thus gradually increasing the liquid purity. The microfiltration membrane layer 41, ultrafiltration membrane layer 42, and nanofiltration membrane layer 43 are connected to a collection tank 9 via pipes along the inner wall of the multilayer membrane separator 4 on one side of the cavity formed above. This collection tank 9 is used to collect the filtrate containing impurities after filtration to a certain stage. Each pipe connection is equipped with a corresponding valve to prevent high-purity liquid from entering the collection tank 9.

[0019] The bottom pipe of the multilayer membrane separator 4 is connected to the circulation tank 5. The circulation tank 5 is equipped with a reverse osmosis membrane. The circulation pipe 51 is located in the circulation tank 5 outside the reverse osmosis membrane, which is used to further add the obtained precision liquid into the reaction cycle.

[0020] All the connecting pipes of the above equipment are equipped with corresponding valves, and the type of filter membrane is selected according to the composition of the waste liquid and the properties and purity requirements of the circulating precision liquid.

[0021] Working principle: The circulating waste liquid enters the waste tank and is initially filtered through a funnel-shaped filter screen. Larger impurities such as suspended solids are filtered through a microporous membrane. After entering the evaporator, the liquid permeates through a reverse osmosis membrane to evaporate. After condensation in the condenser, gaseous impurities are discharged through the exhaust pipe after adsorption treatment. The remaining liquid enters a multi-layer membrane separator and is gradually filtered through microfiltration, ultrafiltration, and nanofiltration membrane layers to obtain high-purity recovered liquid. The liquid is introduced into the circulation tank and further filtered through a reverse osmosis membrane to obtain a circulating liquid with even higher purity, which can be added to the reaction for recycling.
